Auto Hide Rows with 0 Total?

I have a big spreadsheet of all our employees that I use tot rack meals charged at the cafeteria. I end up spending alot of time hiding and unhiding rows that have no charges. I have the names in column A and then each day to the right where they charge, I put the date. At the last column it counts across and down.

Is there a way to tell it to hide all rows with a total = 0? then I can unhide them again to see them all when I'm entering them.

Thanks
